Stone of Valhalla - Mikey Brooks - Bog

Breaking into an old lady's basement was supposed to reward Aaron with new friends. Instead he finds an enchanted amulet that transports him to another world-one at war with magic. Before he knows it, he is accused of witchcraft and forced to attend a bonfire-where he's the main attraction. If that's not bad enough, a goblin army shows up and toasts the town...literally. The good news: Aaron escapes being charbroiled. The bad news: the goblins are after him. They want his amulet and will stop at nothing to get it. Battling to find his way home, Aaron teams up with a not-so-magical-wizard and learns it's his fate to destroy the amulet and save this new world. But is he willing to sacrifice his own?
